Hello, just wondered if anyone could offer any advice as I'm in a bit of a fix!
I temporarily moved out of my house just after Christmas as it had secondary flooding - there was loads of rising damp all over downstairs & it was off the scale when they tested with damp meters. The house is a mid terrace built in 1896.
The downstairs of the house was gutted, floors up, kitchen out, all plaster stripped to halfway up the walls & dryers & dehumidifiers were in for 3 months. A DPC was then injected into the mortar between the bricks. I then got a drying out certificate & work was started to reinstate everything.
The house has been replastered (with a concrete render under the plaster, not plaster board) & the plaster has now been painted. About 2 months after the plastering was done a few damp patches have appeared just above the skirting boards, all in the same places as before. A couple of the patches look like dark water marks & are damp to the touch. The other patch has bubbled the plaster. I've been told not to worry, that's it's normal & is the salts coming out the brick & the remaining damp drying. I am worried though, as no-one seems to be able to tell me conclusively it's not rising damp again, & surely if I've had a drying out certificate the walls should have been dry, so nothing should be coming through the plaster at this stage, unless it's rising damp again?
I just wondered if anyone could tell me if this is normal as I have no idea about these things!
Thanks for reading!
